Mrs. Rios puts tape around the section of wall shown to indicate the area of the mural she will paint. What is the area of the section she wants to paint?
Answers
The area of the section she wants to paint is 48 square feet.
In Euclidean Geometry, the area of a rectangle can be calculated by using this formula;
Area of rectangle = length × width
Area of rectangle 1 = 4 × 9
Area of rectangle 1 = 36 square feet.
For the area of rectangle 2, we have;
Area of rectangle 2 = 4 × 3
Area of rectangle 2 = 12 square feet.
Now, we can find the area of the figure;
Area of figure = 36 + 12
Area of figure = 48 square feet.

What fraction of guests order the signature dish?
Answers
Answer:
11/20
Step-by-step explanation:
Answer: [tex]\dfrac{11}{20}[/tex] represents the fraction of guests order the signature dish.
Step-by-step explanation:
Since we have given that
Percentage of guest who order the signature dish = 55%
Total percentage = 100
We need to find the fraction of guests order the signature dish.
So, Fraction of guests order the signature dish is given by
[tex]\dfrac{\text{Percentage of guest order the signature dish}}{\text{Total percentage}}\\\\=\dfrac{55}{100}\\\\=\dfrac{11}{20}[/tex]
Hence, [tex]\dfrac{11}{20}[/tex] represents the fraction of guests order the signature dish.

Each year, the number of students taught by Mr. Wright increases by 2. The first year, he taught 18 students. The total number of students taught after 25 years can be represented using the expression . How many students has Mr. Wright taught in 25 years?
450
500
1,050
2,100
Answers
1st yr = 18 students
25 yrs = x
Cross multiply
x = 18 × 25
x = 450
Answer:
Mr. Wright taught 1,050 students in 25 years.
Step-by-step explanation:
Given,
The number of students Mr. Wright taught = 18,
Also, every year the number of student is increased by 2,
So, in second year, the number of students = 18 + 2 = 20,
In third year = 20 + 2 = 22,
In fourth year = 22 + 2 = 24,
.............., so on,
Hence, we get an A.P. that shows the given situation,
18, 20, 22, 24, ............. till 25 years.....
First term, a = 18,
Common difference, d = 2,
And, number of terms, n = 25,
Hence, the total number of students that have been taught by him are,
[tex]S_n=\frac{n}{2}[2a+(n-1)d][/tex]
[tex]S_{25}=\frac{25}{2}[36+(25-1)2][/tex]

Name the angle in 2 different ways and name the 2 rays from the diagram below please show work
Answers
Answer:

Step-by-step explanation:
3) those two rays intersect to form the angle shown in the diagram
4) an angle can always be named from left to right or right to left as long as the middle letter is always the vertex of the angle
for number 3 remember the definition of a ray which is a point that has a line sticking out of it that doesn't end and doesn't cause the line to follow the definition of a line segment. BT and BN follow this definition .
for number 4 remember that naming angles is pretty much consistent as left to right and right to left. but either way the same letter should be in the center and the same three letters should be involved. so u get KLM and MLK

The question involves solving algebra and geometry problems related to parallelograms, focusing on transformations, coordinates, and area calculations to find the equation for y.
Explanation:The student is asked to solve a series of algebra and geometry problems related to the properties of a parallelogram. These include finding coordinates, proving algebraic expressions, computing distances, and determining areas. The goal is to find the equation for y given a series of transformations and conditions on a square that becomes a parallelogram. Important concepts include the area of a parallelogram, vector addition using the parallelogram rule, and the determinant relating to a change of basis in vectors.
For example, part (e) involves finding the area of the parallelogram by computing twice the area of triangle PQO, using PQ as the base of the triangle. Solving for y in part (f) by setting this area equal to 1 involves understanding the effects of transformation on geometrical shapes and employing algebra to arrive at the desired equation.

Jian’s family sells honey from beehives. They collected 3,311 ounces of honey from the beehives this season. They will use the honey to completely fill 4-ounce jars or 6-ounce jars. Jian’s family will sell 4-ounce jars for $5 each or 6-ounce jars for $8 each. Jian says if they use only 4-ounce jars, they could make $4,140 because 3,311 / 4 =827 R3. That rounds up to 828, and 828 multiplied by $5 is $4,140. Part A-Explain the error that Jian made when finding the amount of money his family could make if they use only 4-ounce jars. Enter your explanation in the space provided. Part B- Explain how to determine the money Jian’s family could make if they use only 6-ounce jars. Include the total amount of money and the total number of 6-ounce jars in your explanation. Enter your answers and your explanation in the space provided.
Answers
Answer:
A. Jian rounded the number of 4-ounce jars to 828 which is wrong. There are only 827 jars that can be completely filled.
B. Total number of 6-ounce jars = 551
Total money earned from 6-ounce jars = $4408
Step-by-step explanation:
A. Jian's family's collection = 3311 ounces
Number of 4-ounce jars = [tex]\frac{3311}{4}[/tex]
= 827.75
Jian rounded it to 828 which is wrong. There are 827 jars that can be completely filled.
Cost per 4-ounce jar = $5.
Total cost = 827 × 5 = 4135
B. Now, number of 6-ounce jars = [tex]\frac{3311}{6}[/tex]
= 551.83
≅ 551 jars
Cost per 6-ounce jar = $8
Total cost = 551 × 8 = 4408

Answers
Answer:
Huma's share =Rs x = Rs. 1.35392881
Seema's share =Rs. 12x = Rs (12 * 1.35392881) = Rs. 16.2471457
Hubna's share =Rs. 123*12x = Rs. (123*16.2471457) = Rs. 1998.39892
Step-by-step explanation:
Given :
Huma , Hubna and Seema received a total of ₨2,016 as monthly allowance from their mother.
Seema gets 12 of what Huma gets
Hubna gets 123 times Seema’s share
To find : How much money do the three sisters get individually?
Solution :
Let Huma's share be Rs. x.
Since we are given that Seema gets 12 of Huma's share
⇒ Seema's share = Rs 12x.
Since we are given that Hubna gets 123 times Seema’s share
⇒Hubna's share = Rs. (123 * 12x) = Rs. 1476x.
We are given that they received together Rs. 2016 in total .
⇒[tex]x+12x+1476x= 2016[/tex]
⇒[tex]1489x= 2016[/tex]
⇒[tex]x = \frac{2016}{1489}[/tex]
⇒[tex]x = 1.35392881[/tex]
Thus Huma's share =Rs x = Rs. 1.35392881
Thus Seema's share =Rs. 12x = Rs (12 * 1.35392881) = Rs. 16.2471457
Thus Hubna's share =Rs. 123*12x = Rs. (123*16.2471457) = Rs. 1998.39892

you are a plumber installing a pipe the ratio of the outside diameter to the inside diameter is 1.5 to 1. you use a pipe with a 0.5 inch inside diameter what is the smallest diameter that you will need to drill to allow the pipes to pass through the wall
Answers
So the smallest diameter possible would be 0.75 inches.
The smallest diameter needed to drill through the wall is 0.75 inches, which is calculated by multiplying the inside diameter of the pipe (0.5 inches) by the ratio of the outside diameter to the inside diameter (1.5). Always measure and plan ahead to avoid mistakes.
Explanation:The subject matter of this question is mathematics, specifically ratios. To find the smallest diameter you would need to drill into the wall, you would need to multiply the inside diameter of your pipe (0.5 inches) by the ratio of the outside diameter to the inside diameter (1.5). So, 0.5 inches * 1.5 = 0.75 inches.
This means, to allow the pipes to pass through the wall, you will need to drill a hole at least 0.75 inches in diameter. This is assuming the wall is thin enough that the entire length of the pipe that needs to pass through the wall is less than the thickness of the wall.
Remember, it's always better to pre-measure and plan ahead to avoid unnecessary work and potentially costly mistakes.

Your parents are renting an apartment for you when you go away to college. An annual contract is $502.00/month with a 2-month penalty if you break the lease. The month-to-month contract is $615.00/month. How much is the difference in payments if you stay the whole year?
Answers
Answer:
The month-to-month contract will cost an extra $1356.
Step-by-step explanation:
"An annual contract is $502.00/month with a 2-month penalty if you break the lease."
If you stay the whole year, and you pay $502 per month, you pay 12 * $502 = $6024 for the entire year.
"The month-to-month contract is $615.00/month."
If you stay the entire year, you pay 12 * $615 = $7380.
The difference is $7380 - $6024 = $1356
